摘要： A female element (1) is described comprising a hollow internal body (2) having an end (3) provided with fastening means (5) to one of the pipes to be joined, a hollow external body (7) coaxial with said internal body (2) and having an end (8) which axially protrudes with respect to another end (4) of the internal body (2) opposite to that provided with fastening means (5), one rigid central stem (9) coaxially supported by said internal body (2) by means of a transversal perforated base (18) and having a widened end (10) near said protruding end (8) of the external body (7), an axially sliding sealing bush (12) coaxially arranged about said stem (9) and elastically stressed to be engaged with said widened end (10) of the stem (9) to prevent the passage of fluid within the female element (1), a cleaning bush (14) coaxially arranged about the sealing bush (12) and axially stressed in position so as to prevent the entrance of dirt about the sealing bush (12) and a lock sleeve (16) arranged about the protruding end (8) of the external body (7) and engageable with a complementary end of a male element to ensure the stable union of the two male and female elements of the fitting. The stem (9) is fixed to said base (18) by means of at least one half bush (25) radially fitted and axially locked in corresponding seats (26, 27) of said stem (9) and said base (18) (FIG. 1).

摘要： A quick coupling includes a first element and a second element which may be separably coupled. The first element includes a connector for connecting to a user interface, an external sleeve having helicoidal grooves and seats, and a first valved coupling for a first pressure line. The second element includes a hooking ring nut, a plurality of internal pins, a compression spring, a second valved coupling for a second pressure line, and a connector. The second element further comprises a safety ring nut and a plurality of safety pins provided along a circumference of the safety ring nut, the safety pins being configured to axially slide with the safety ring nut. The safety pins are configured to be pushed by the hooking ring nut and the compression spring into the seats of the external sleeve.
